Abstract

This study comprehensively assesses safe loading conditions for the Self-Propelled Crane Barge (SPCB) Deck Crane by integrating detailed hydrostatic calculations with righting-arm (GZ) curve analysis. At the designated summer draft of 2.75 m, baseline parameters—displacement (1 716 t), centre of buoyancy (KB = 0.765 m), transverse metacentre (KM = 2.780 m), and metacentric height (GM = 1.23 m)—were established from the vessel’s stability booklet. Four loading scenarios (lightship, full ballast, crane at maximum outreach, and cargo distribution) were defined, with updated displacement and vertical centre of gravity (KG) values used to recompute hydrostatic parameters (BM, KM, free-surface corrections) and generate full GZ curves. Intact-stability criteria (GM ≥ 0.15 m, area under GZ curve ≥ 0.08 m·rad, angle of vanishing stability ≥ 25°, and GZmax ≥ 0.25 m) were evaluated for each case. Results indicate that the ballast condition yields the highest stiffness (GM ≈ 1.50 m) and energy absorption (AUC ≈ 1.15 m·rad). The crane-outreach scenario represents the narrowest margin (GM ≈ 0.90 m, AUC ≈ 0.60 m·rad). A safe-loading envelope was developed, showing permissible crane loads of up to 100 t at 10 m outreach and limiting lifts beyond 20 m to 50 t or less. Mitigation measures—ballast management, outreach/load restrictions, optimized cargo stowage, and real-time monitoring—are recommended to ensure regulatory compliance and operational safety.

Abstract

Aging offshore platforms require a reliable drainage system to ensure safety and operational efficiency. This study aims to analyze the adequacy of the closed drain and open drain systems on a 24-year-old offshore platform that is scheduled for redevelopment. The methodology employed involves hydraulic analysis, considering fluid production rates and drainage system design data based on API 14E and GPSA (2004) standards. The collected data included channel cross-section dimensions, flow rates, and fluid characteristics to calculate the system's capacity. The analysis showed that the 4-inch header pipe was adequate to accommodate a closed drain flow rate of 167.4 BPD and an open drain flow rate of 1.63 BPD. The Slop Tank (Platform X-T-26), with a geometric volume of 54 ft3, was also adequate to contain the maximum drainage volume of 15.23 ft3 from the Vertical Test Separator. This study also identified several critical points that require periodic monitoring to prevent blockages and performance degradation. This study emphasizes the importance of periodic inspections to assess the adequacy of drainage systems on aging offshore platforms to ensure safety and operational efficiency after redevelopment. It also provides preventive maintenance recommendations to extend the system's lifespan.

Abstract

This research aims to analyze the factors that cause overflow in the fuel oil purifier system and to identify measures that can be taken to address this issue using the Failure Mode and Effect Analysis (FMEA) method. Overflow in the fuel oil purifier can disrupt the fuel purification process, which is crucial for engine performance. Therefore, understanding the causes and appropriate solutions is essential. The analysis results indicate that the factors causing overflow include leakage or wear of vital components such as O-rings, gravity discs, belts, bowls, main seal rings, ball bearings, nozzles, and pilot valves, as well as improper installation of components or blockages due to debris obstructing the flow. Overflow can be managed through regular inspections of components prone to wear or damage, routine cleaning of components that are susceptible to clogging, and continuous monitoring and calibration of the system to ensure the purifier operates optimally. By implementing these measures, the fuel oil purifier system is expected to function efficiently, reduce the risk of overflow, and enhance the reliability of the fuel purification process.

Abstract

The motor is a crucial component of a ship's propulsion system, playing a significant role in facilitating smooth maritime transportation operations. Various factors, including dynamic loads, speed variations, and unstable marine environmental conditions influence the performance of the propulsion motor. Under dynamic conditions, the ship's propulsion motor encounters challenges such as load fluctuations, vibrations, and other disturbances that can affect its efficiency and operational lifespan. Consequently, real-time monitoring of the motor's condition has become an urgent necessity to detect potential damage early and ensure the safety and reliability of the ship's operations. This study aims to develop a condition monitoring system for ship propulsion motors using nonlinear acoustic signals. These signals will be processed using appropriate algorithms for nonlinear signals' characteristics. The Short Time Fourier Transform (STFT) is identified as a suitable algorithm for processing nonlinear signals. The filtered signal results will provide insights into the condition of the ship's propulsion motor. Given the influence of vibrations and non-engine noise, careful consideration must be given to sensor placement to achieve high monitoring accuracy. The Completely Randomized Design (CRD) approach will be employed to determine the optimal sensor placement. Through precise signal processing, meticulous spectral analysis, and optimal sensor positioning, accurate information can be obtained. The research findings indicate that the motor monitoring system achieved an accuracy rate of 100% with the sensor positioned 110 cm from the test motor body.

Abstract

Fatigue life analysis is often overlooked in ship development, leading to an uncertain understanding of a ship’s construction lifespan. This study focuses on the fatigue life of the car deck, which is affected by deformation on a ro-ro ferry. The research aims to determine the maximum stress, location, the cause of deformation, and the fatigue life of the car deck on a ro-ro passenger ship. The calculations assess the car deck’s lifespan and provide a reference for future design considerations. Finite element analysis (FEA) is used, with fatigue life calculated using the Sonderberg method. The research begins with calculating the ship’s weight and buoyancy distribution, then determining the ship’s longitudinal strength from the load distribution. The analysis reveals that the highest stress occurs under hogging wave conditions, exceeding the yield strength of 321 MPa. Specifically, at overload and hogging wave conditions, the highest stress of 486.1 MPa is found on the starboard side between longitudinal stiffeners 1 and 2 (900 mm from the centerline), between frames 56 and 57, with a fatigue life of 4.3 years.

Abstract

This study investigates the integration of a solar photovoltaic system on the passenger ferry E.V. Calestia operating along Manila’s Pasig River. The ferry, equipped with dual 400 kW electric motors and a battery bank of 1848 kWh, is supplemented by 20 solar panels installed on its top deck. Using a Simulink-based simulation model, the research estimates the power output and cumulative energy generation based on panel specifications, solar irradiance, and system efficiency. Results show a maximum instantaneous power output of approximately 3 kW during peak sunlight and a total weekly energy generation of around 150 kWh. These findings demonstrate the potential of solar power to enhance the ferry’s energy sustainability by reducing reliance on conventional charging and lowering emissions, thus promoting greener maritime transport solutions in urban river environments.

Abstract

This paper presents a comprehensive structural integrity assessment of a 50,000-kiloliter aboveground steel storage tank that experienced shell denting during hydrostatic testing. Dents and geometric imperfections are known to significantly affect the buckling behavior and load-bearing capacity of storage tanks. To evaluate the tank’s fitness for service (FFS), a Level 3 assessment was conducted following API 579-1/ASME FFS-1 Part 8 standards. Finite element analysis was employed to simulate the elastic stress distribution and fatigue behavior under various loading conditions, including hydrostatic pressure, wind, and seismic loads. Results revealed that shell course 7 and 8 experienced stress increases of up to 2282% compared to the undistorted condition, with von Mises stress remaining below the allowable limits. A fatigue analysis confirmed that stress amplitudes were below the fatigue threshold, resulting in infinite fatigue life. Furthermore, discharge simulation indicated that improper dewatering could induce external pressure exceeding the material’s yield strength, leading to localized plastic deformation. Nevertheless, the dented tank was found to be structurally sound and compliant with API 650 and API 579-1/ASME FFS-1 criteria. The study highlights the importance of proper discharge procedures and confirms that no immediate repair is required for continued safe operation of the tank.

Abstract

Load cell is an critical component in the tandem lifting system using a mobile crane that functions to measure the load accurately. Damage to the load cell can cause operational failure and increase the risk of accidents. This study aims to analyze the potential for load cell damage using the Fuzzy Fault Tree Analysis (FFTA) approach. FFTA combines fault tree logic with fuzzy theory to clarify risk assessment. By collecting data from study literature, interviews and historical equipment data, the analysis results obtained that the factors causing load cell damage include overload factors, damage factors to load cell components and environmental factors. And through the FFTA method, namely the damage factor to the load cell component with a weighting value of 0.1840 or 47%. The contribution of this study is to provide a systematic approach to identifying and evaluating the risk of load cell damage, which can be used as a basis for improving inspection programs and preventive maintenance on tandem lifting using a mobile crane. This approach can also support management decision making in improving the reliability and safety of lifting equipment.
